Abstract
Abstract Apparatus for the in situ formation of and application to electrical insulator parts, of gaskets and pads, preferably of mica fibers, which gaskets and pads are interposed between the interfaces of the parts in their final assembled and rigidly interconnected relation. A rotor turnable about a fixed vertical axis has arms which are automatically and sequentially indexed to a plurality of fixed work stations. Each alternate one of the arms supports a first part, while each of the remaining arms supports a second part which is to be assembled with a first part. At one station means apply a coating of adhesive to the area of the part over which a gasket or pad is to be formed. At a second and subsequent station, flocking is applied to the adhesive-coated area, and at a third station excess flocking adhering to areas not coated with adhesive, is removed and collected for reuse. The flocking may be applied electrostatically to form in situ, a gasket wherein the fibers are parallel and upstanding like the bristles of a brush.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
The apparatus of claim 1, said first means comprising a first container for adhesive, an inflatable sphere of resilient material, means journaling and rotating said sphere within said container about an essentially horizontal diameter thereof, and means responsive to indexing of each arm, in sequence, into said first position, to translate said rotor from said elevated to said lowered position and thereby move the element carried thereby into contact with said sphere.
Claim 2
Dependent Claim
51 words
The appAratus of claim 2, a motor connected with said sphere to rotate the same about said diameter thereof, a normally closed circuit energizing said motor and including switch means opened by and in response to approach of the element at said first station toward said sphere, to open said circuit.
Claim 3
Dependent Claim
75 words
The apparatus of claim 1, said second means comprising a second container for flock, first and second cylindrical brushes, means journaling said brushes in said second container for rotation on spaced parallel axes, means connected with said brushes for rotating the same oppositely, and means engaging and deflecting the bristles of said brushes as they approach an element indexed at said second station, to effect a spray of flock onto and over the element thereat.
Claim 4
Dependent Claim
93 words
The apparatus of claim 1, said first-named means comprising a plurality of fluid pressure-operated means each carried by a respective one of said arms for rotation as a unit therewith, each said fluid pressure-operated means including a holder vertically movable by and in response to introduction of fluid under pressure thereinto, each holder carried by each said alternate arm having a bulbous depending end releasably fitting in a cap element, each holder carried by the remaining arms having a depending recessed end to receive and removably hold a bulbous end of a stem.
Claim 5
Dependent Claim
37 words
The apparatus of claim 5, each said fluid pressure-operated means comprising a vertically disposed fluid pressure cylinder, piston and rod, each said holder being detachably secured to the projecting end of a respective one of said rods.
Claim 6
Dependent Claim
112 words
The apparatus of claim 6, a plurality of containers each fixed at a respective one of said first, second and third work stations and enclosing a respective one of said first, second and third means, and a plurality of covers each fixed with a respective one of said rods and positioned thereon to fit down over the container over which it is indexed, by and in response to downward movement of its rod, controller means operated in timed relation with rotation of said rotor, and valve means operated by said controller to introduce fluid under pressure into each said cylinder substantially simultaneously with indexing of said arms into said stations, as aforesaid.
Claim 7
Dependent Claim
171 words
The apparatus of claim 1, first, second and third fluid pressure-operated means each fixed at a respective one of said work stations, each said fluid pressure-operated means including a member vertically reciprocable over the arm indexed at its station, said first-named means including a vertically reciprocable rod, each said rod having its upper end below and spaced from a corresponding one of said members when said rotor is in indexed position, a controller operated in timed relation with said rotor, and valve means operated by said controller to substantially simultaneously introduce fluid under pressure into all said fluid pressure-operated means, by and in response to movement of said rotor into indexed positions, thereby moving said members and rods downwardly, and first, second and third containers at said respective stations, each enclosing a respective one of said first, second and third means, and positioned to receive the elements carried by the arms indexed at the respective stations when moved downwardly in response to introduction of pressure fluid into said fluid pressure-operated means.
Claim 8
Dependent Claim
17 words
The apparatus of claim 8, and means yieldingly urging each said rod into a limiting upward position.
Claim 9
Dependent Claim
101 words
In an apparatus for the production of electrical insulators of the type described, a container for adhesive, a hollow resilient part mounted in said container for rotation about an axis of symmetry thereof, power driven means connected with said hollow resilient part to rotate the same about said axis, means operable to move an element of an insulator over said part, means energized in response to indexing of the element over said part, to lower said element into contact with said part, and means responsive to lowering of said element adjacEnt to said part to render said power driven means ineffective.
Claim 10
Dependent Claim
20 words
The apparatus of claim 10, said power driven means including a clutch, said last-named means operating to open said clutch.
